SHOE SOLE AND PROCESS OF MAKJQNG THE SAME.

Application filed October 29, 1921. Serial No. 511,305.

To all whom it may concern:

Be it known that I, Mrcrme GONZALEZ Munoz, a. citizen of the Republic ofMexico, residing at Mexico city, Mexico, have invented new and usefulImprovements in Shoe Soles and Processes of Making the Same, of whichthe following is a specification.

This invention relates to the art of shoemaking and has especialrelation to a novel construction of shoe sole and the process of makingthe same.

The primary object of the invention is the provision of a shoe solewhich is constructed so that its inner face is shaped to conform to theshape and character of the sole face of the shoe, so as to provide aperfeet fit and prevent the passage of moisture between the shoe and itssole.

For this purpose, the invention also includes means for making the sole,whereby this fit is obtained, the inner face of the sole conformingperfectly to the irregularities of the sole face of the shoe to which itis attached.

With the above and other objects in view, the invention further includesthe following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claims.

In the drawings Figure 1 is a bottom view looking at the sole face of ashoe and showing the inturned edges of the upper.

Figure 2 is a top View of a mould core made from this face of the shoe.

Figure 3 is a bottom view of the same.

Figure 1 is a longitudinal section through a mould with the core inplace.

Figure 5 is an inner plan view of one mould member.

Figure 6 is a similar view of the other mould member.

Figure 7 is an inner face view of a sole made from the mould.

Figure 8 is a longitudinal section through the mould with a soletherein.

Figure 9 is a transverse section showing the sole attached to a shoe.

Referring to the drawings in detail, like characters of reference denotecorresponding parts throughout the several views...

In carrying out the invention, the sole of the shoe is formed of somesuitable composition which is capable of being moulded, the purposebeing, as stated, to produce a shoe sole having a perfect fit upon theshoe. to which it is attached. In order to make this sole,'a mould isprovided which will produce a sole whose inner face (that is, the facewhich contacts with the bottom) conforms perfectly to the shape andirregularities of the sole face of the shoe. To accomplish this theshoe, after the upper has been secured in place, as shown in Figure 1,is used to construct a mould core, one face of this core being made fromthe bottom or sole face of the shoe. The opposite face of the core ispreferably, though not necessarily shaped to provide a combined sole andheel.

The core which is indicated at 10, has its inner face 11 shaped toprovide a centrally raised portion 12 and a depressed marginal portion13, the former being made by the sole face 15 of the shoe and the latterby the inturned edges 16 of the upper. As the member is cut as at 17 sothat its inturned flange 16 will lie substantially flat, the spaceprovided by these cuts form marginal raised portions or lugs 18, asshown in Figure 2 of the drawings. The bottom face of the core isillustrated in Figure 3 and includes the tread face 19 of the sole andthe heel 20.

While it is preferred to form the sole and illustrated in Figure 4 ofthe drawings and I may be made of any suitable material. The member 21of the mould is thus formed with a centrally depressed portion 23 whichconforms to the irregularities and surface of the bottom or sole face 15of the shoe, while a depressed marginal edge 24 is also provided toreceive the inturned edges 16 of the shoe upper. Marginal depressedportions 25 extend inward from the marginal portion 24 The other mouldmember 22 is shaped to provide a proper thickness of sole and heel asindicated at 26 and 27 respectively.

The shoe sole which is indicated at 28 is formed within this mould, themember 21 forming a centrally raised portion 29, :1 marginal depressedportion 30 and projecting portions or lugs 31. The centrally raisedportion 29 will thus occupy the space between the inturned edges 16 ofthe shoe upper, while the marginal depressed portions 30 will receivethis edge, with the projecting portionsv or lugs 31 occupying the spacesprovided by the cut away portions 17 of the upper flan e 16.

The sole may e secured to the shoe in any suitable or desired manner andwhen so secured, Will provide a perfect fit between its inner face andthe sole face, and in addition to its many other advantages, will act toretard the passage of moisture between the sole and shoe.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaims.

Having described the invention what is claimed is:

1. The herein described process of making shoe soles consisting offorming a core, one face of which is formed by the sole face of the shoeafter-the edges of the upper have been turned inward and attached;making 'a mould from saidcore and then moulding the sole therein, sothat the contacting faces of the shoe and sole will provide perfectengagement.

2. The herein describedprocess of making shoe soles consisting of usingthe sole face of a shoe after the edges of the upper have been turnedinward and secured, for the purpose of forming a mould and of thenmoulding the sole therein, so that. the contacting faces of the shoe andsole will provide perfect engagement.

In testimony whereof I aflix my signature MIGUEL GONZALEZ MUNOZ.
